6th Gr Unit 4 Forces and Chemical Change

Front

What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined. It determines the object's motion.

Front

How do you calculate net force?

Back

Net force is calculated by adding all the forces acting on an object. If forces are in opposite directions, subtract the smaller force from the larger force.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It has the potential to be converted into kinetic energy.

Front

At which point in a pendulum's swing is potential energy the greatest?

Back

Potential energy is greatest at the highest points of the swing (points 1 and 5).

Front

What is a chemical change?

Back

A chemical change is a process where substances combine or break apart to form new substances, often accompanied by energy changes.

Front

What is evidence of a chemical change?

Back

Evidence of a chemical change includes production of gas, color change, temperature change, and formation of a precipitate.

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

Front

What is normal force?

Back

Normal force is the support force exerted upon an object that is in contact with another stable object, acting perpendicular to the surface.

Front

What is applied force?

Back

Applied force is a force that is applied to an object by a person or another object.

Front

What is frictional force?

Back

Frictional force is the force that opposes the motion of an object when it is in contact with another surface.
